JP 2006-36090 A

  A robot arm may be used for assembling the lock pin together with the spring to the lid of the console box. In that case, if the outside of the lock pin is gripped by a hand-type tool of the robot arm, the tool becomes obstructed when the lock pin is inserted into the narrow space of the lid, and cannot be assembled properly. Also, the robot arm tool needs to adopt a special holding structure so that the lock pin cannot be easily removed.

  An object of the present invention is to solve such a problem, and an object of the present invention is to make it possible to easily assemble a lock pin even in a narrow space of a lid of a console box and to employ a special holding structure. It is possible to hold the lock pin so that the lock pin cannot be removed without it.

The present invention is for achieving the above object, and is configured as follows.
A pair of lock pins and a spring interposed between both lock pins are assembled to the lid of the console box, and both lock pins receive the biasing force of the spring and can lock the movement of the lid. A console box locking mechanism capable of moving the lid by releasing the lock, and a pair of lock pins having a clamp hole into which a pair of clamp members provided on the robot arm can be individually inserted Each has. And in the state which the clamp member was inserted in each clamp hole, it sets so that both lock pins may be hold | gripped in the state which compressed the spring.

  A method of assembling the console box locking mechanism, wherein a pair of lock pins are set with a spring interposed therebetween, and a pair of clamp members of the robot arm are individually inserted into the clamp holes of both lock pins. After the insertion, both the lock pins are brought close to each other by the operation of both clamp members to compress the spring, and in this state, the robot arm is operated to assemble the both lock pins together with the spring to the lid of the console box.

In the present invention, by inserting the clamp members of the robot arm individually into the respective clamp holes of the pair of lock pins, these lock pins can be held together with the spring interposed therebetween. Thus, unlike the case where the lock pin is gripped from the outside by a hand type tool of the robot arm, the lock pin can be assembled even in a narrow space of the lid in the console box.
In addition, since both lock pins are gripped by the clamp member in a state where the spring is compressed, the elasticity of the spring can be used to keep the clamp member and the lock pin from coming off. It becomes unnecessary to adopt a holding structure.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
The lid 10 of the console box shown in FIG. 1 can be opened and closed with respect to the box body (not shown) and can be slid in the front-rear direction of the vehicle body. The inner structure of the lid 10 is mainly composed of an inner plate 12 and a hinge member 18 shown in FIG. 2, and an outer plate 14 (including a pad and an outer skin) and a side plate 16 shown in FIG. Has been.
The inner plate 12 is assembled to the hinge member 18 so as to be slidable in the front-rear direction. The hinge member 18 is supported so as to be openable and closable with respect to the box body.

  As shown in FIGS. 2 and 3, the inner plate 12 has a concave portion 12 a that is continuous in the left-right direction. A pair of lock pins 20 and one spring 26 are assembled to the recess 12a. Both lock pins 20 have their spring seats 22 facing each other, and a spring 26 is interposed between these spring seats 22 (FIG. 4). A plurality of ribs 12b are formed on the inner wall of the recess 12a to come into contact with the lock pins 20 (FIG. 3). These ribs 12b reduce the contact area between the inner wall of the recess 12a and both lock pins 20, and smooth the movement of the lock pin 20 moving in the left-right direction within the recess 12a.

Both lock pins 20 assembled in the recess 12 a receive a biasing force in a direction to be pushed away from each other by the elasticity of the spring 26. With this urging force, the lock pin 20 is kept engaged with a hole or the like (not shown) on the hinge member 18 side, and the slide of the inner plate 12 (lid body 10) with respect to the hinge member 18 is locked.
Then, in conjunction with the operation of the release knob or the like, both lock pins 20 move toward each other against the biasing force of the spring 26, and the lock is released. As a result, the inner plate 12 (lid body 10) can be slid relative to the hinge member 18.

As shown in FIG. 5, the tool head 31 of the robot arm 30 for assembling the lock pin 20 includes a pair of clamp members 32. And a pair of lock pin 20 is each provided with the clamp hole 24 penetrated up and down, and a pair of clamp member 32 can be inserted into these clamp holes 24 separately (FIG. 6). The clamp holes 24 of both lock pins 20 have a rectangular shape and are set to have an opening size sufficient for inserting the clamp member 32. On the other hand, the tool head 31 of the robot arm 30 can be controlled to change the distance between the clamp members 32.
Therefore, by reducing the distance between the clamp members 32 inserted into the clamp holes 24 of the lock pins 20, the lock pins 20 compress the springs 26 and approach each other. Due to the restoring elasticity of the spring 26, both lock pins 20 are gripped so as not to be disengaged from both clamp members 32.

Next, a procedure for assembling the pair of lock pins 20 together with the spring 26 to the recess 12a of the inner plate 12 in the lid 10 by the robot arm 30 will be described. First, as shown in FIG. 6, both lock pins 20 and the spring 26 are set on the jig 40. The spring 26 in this set state is located between the spring seats 22 of the two lock pins 20.
Next, the robot arm 30 is operated to insert the clamp members 32 of the tool head 31 into the clamp holes 24 of the lock pins 20 individually. Thereafter, by reducing the distance between the clamp members 32 as described above, the lock pins 20 are held by the clamp members 32 in a state where the springs 26 are compressed.

The pair of lock pins 20 and the spring 26 gripped by the clamp member 32 are carried from the jig 40 to above the recess 12a of the inner plate 12 by the operation of the robot arm 30 (FIG. 7). Here, by lowering the tool head 31, both the lock pins 20 and the spring 26 are assembled to the recess 12a (FIG. 8).
In this state, the distance between the clamp members 32 is increased, the compression of the springs 26 by the lock pins 20 is released, the tool head 31 is raised, and the clamp members 32 are extracted from the clamp holes 24 of the lock pins 20 ( FIG. 9). Thus, the assembly of the pair of lock pins 20 and the spring 26 to the recess 12a of the inner plate 12 is completed.

  Thus, by inserting the clamp members 32 into the clamp holes 24 of the pair of lock pins 20 and gripping these lock pins 20 together with the springs 26, the lock pins 20 can be placed in a narrow space such as the recess 12 a of the inner plate 12. Can be assembled accurately. Further, since both the lock pins 20 are gripped in a state where the springs 26 are compressed, both the lock pins 20 can be held so as not to be detached from the clamp member 32 without using a special holding structure.

As described above, when the spring 26 interposed between the two lock pins 20 is compressed, the outer lower portion shifted from the axis connecting the mutual spring seats 22 (the axis of the spring 26) in the two lock pins 20 is the spring. There are cases in which it is opened outward by the restoring elasticity of 26. This problem can be solved by allowing the clamp holes 24 of both the lock pins 20 to penetrate vertically and allowing the clamp members 32 to be sufficiently inserted through the clamp holes 24.
As another countermeasure for the same problem, an engagement groove may be provided on one of the inner wall surface of the clamp hole 24 and the outer surface of the clamp member 32, and an engagement rib that fits into the engagement groove may be provided on the other.

  As shown in FIG. 8, when the lock pins 20 are assembled together with the springs 26 into the recess 12a of the inner plate 12, the lock pin 20 may hit the rib 12b of the recess 12a and damage the rib 12b. As this countermeasure, the edges on both sides of the lower surface 21 (FIG. 6) of both lock pins 20 may be tapered so that the lock pin 20 enters the recess 12a along the rib 12b.
